The Model LZJ-4D Neural surgery, brain surgery, fa

applicationModel LZJ-4D is a light multi-function operation microscope developed by Zhenjiang Zhongtian Optical Instrument Co., Ltd. It can be used in the operations such as brain surgery, ENT, ophthalmology etc. The optical routeway of the microscope adopts the parallel optical routeway and it has the features of big field depth, wide vision field and uniform illumination. If necessary, the single ocular teaching scope, camera interface and CCD interface can be chosen. The instrument also is ideal one for animal dissection and microsurgery teaching.feature1.The parallel optical routeway, main scope and assistant scope withsingle optical routeway. 2.Optical system has the features of big field depth, wide vision fieldand lighting equally. 3.5-level magnification changer:Zooming Ratio:1:6. 4.Motorized focusing by foot control. 5.Cold light source illumination, no heating. 6.
